I think you should get a standalone ECM, regardless of the manufacturer. I promote AEM because I have one and it works very well for me, when it's actually in my car. Cams aren't a minor add-on. They need more and air fuel to see their potential, and they need it at different intervals than your stock cams. Your current maps give you fuel to match your stock cams curves, and most likely won't be sufficient to compensate for the new cams. Piggyback computers are a bandaid.
